java.awt.Component.AccessibleAWTComponent
java.awt.Container.AccessibleAWTContainer
javax.swing.JComponent.AccessibleJComponent
javax.swing.JSlider.AccessibleJSlider
All Implemented Interfaces:
Serializable, EventListener, AccessibleAction, AccessibleComponent, AccessibleExtendedComponent, AccessibleValue, ChangeListener
Enclosing class:
JSlider
protected class JSlider.AccessibleJSlider extends JComponent.AccessibleJComponent implements AccessibleValue, ChangeListener, AccessibleAction
This class implements accessibility support for the JSlider class. It provides an implementation of the Java Accessibility API appropriate to slider user-interface elements.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.
